UNITED NEWS INTERNATIONAL (UNI) — Anyone planning on visiting Mars in the future will have plenty of water.

Scientists found thick sheets of ice on the Red Planet that hint at enormous buried glaciers.

Colin Dundas with the U.S. Geological Survey helped make the discovery by studying images from NASA’s Mars Reconnaissance Orbiter.

Dundas and his team described eight different sites where cliffs jut out of the planet, exposing almost pure water ice, in a study published Jan. 11 in the journal Science.

The icy cliffs are reportedly up to 100 meters tall and hint at huge stockpiles of frozen water lying just a meter or two below the surface.

The cliffs are also located in places that wouldn’t be too hard for visiting astronauts to reach.

Researchers think these icy deposits were created by ancient snow storms and could help us learn more about the past Martian climate.
